The black and white branding was cheap and cheerful, as well as symbolising a firm British Ska value of black & white integration.
This was based on Jamaican ska music arriving in the UK with 1950s Jamaican migration to the UK (and also merchant sailors bringing it home), Jamaican ska in the UK merged with local genres such as punk, new wave etc and also entwined reggae & ska
The UK flavour gained further popularity with 2nd generation Jamaican immigrant and their British peers. It was particularly popular with the skinhead movement (which does not equate to the National Front types wearing the same fashion)
At a ska gig you would find black & white skinheads, (plus the odd NF skinhead who may ‘tolerate’ the blacks at the gig, but kick their heads in the next day)
This is England illustrates the taking over of skinhead styles by the National Front, with scenes between main characters referencing their younger days as close friends sharing parents Jamaican Ska then falling apart with the rise of the NF
